In other words, the head 136 of the support screw 135 protrudes from the lower surface side of the overhanging portion 86A.
Further, a mounting plate 75A provided at the inner edge of the lower surface plate 75 of the front panel 60 is adapted to be brought into contact with the front surface 31A of the bottom plate 31 of the machine room 11, and a screw hole 137 is formed on the front surface 31A of the bottom plate 31. It is formed (FIG. 7).

The present embodiment has the above-described structure, and an example of a procedure for attaching the operation panel 80 and the front panel 60 of the lower chamber 40D will be described.
First, the left reinforcing plate 55 and the upper reinforcing plate 50 are attached to the left side and the upper side of the front surface of the condenser 46, respectively. Here, while the left reinforcing plate 55 is fixed as described above, only the lower portion 51D of the upper reinforcing plate 50 is fixed to the upper surface cover 46A of the condenser 46 with screws 52, as shown in FIG. Thus, the upper portion 51U is fastened to be applied to the flange 36 on the front surface of the partition plate 35.
From this state, as shown in FIG. 16, the upper part of the operation panel 80 in which the left and right cover panels 110 are integrally assembled is placed on the lower surface side of the support frame 120, and the operation panel 80 is gradually raised, as shown in FIG. 16. As described above, when the rising plate 106 at the front edge of the upper surface plate 105 is applied to the back side of the front plate 126 of the support frame 120, the hooked portion 105 </ b> A that is the front edge portion of the upper surface plate 105 is engaged with the support frame 120. It will be in the state latched by the part 127. FIG.

At the same time, the mounting plate 109 provided at the lower edge of the operation panel 80 overlaps the surface of the upper portion 51U of the upper reinforcing plate 50 temporarily fixed, so that the operation panel 80 is moved to the left and right along the latching portion 127. While sliding, the three insertion holes 131A at the center of the mounting plate 109 pass through the insertion holes 132 of the upper reinforcing plate 50, and the insertion holes 131B at both ends pass through the insertion holes 134 of the front plate of the column 32, respectively. Then, alignment is performed so as to align with the screw hole 133 of the flange 36 of the partition plate 35. Then, at the center portion, the screw 53 is passed from the insertion hole 131A of the mounting plate 109 to the insertion hole 132 of the upper reinforcing plate 50, and at both ends, the screw 53 is passed from the insertion hole 131B of the mounting plate 109 to the insertion hole 134 of the column 32. Are respectively screwed into the screw holes 133 of the flanges 36 of the corresponding partition plates 35 and tightened. Accordingly, the mounting plate 109 at the lower edge of the operation panel 80 is fixed to the flange 36 on the front surface of the partition plate 35 with the upper portion 51U of the upper reinforcing plate 50 or the front plate of the pillar 32 sandwiched therebetween. .
At this time, since the operation panel 80 is hooked by the hooking portion 127 and is supported in a suspended state, the operator attaches one hand to the bottom of the operation panel 80 or the like and supports it in a proper position. However, the operation of screwing the screw 53 with the other hand can be performed.

When the operation panel 80 is attached together with the cover panel 110, the front panel 60 of the lower chamber 40D is subsequently attached. When the operation panel 80 (the cover panel 110) is attached, the head 136 of the support screw 135 protrudes from the bottom surface of the cover panel 110. When the front panel 60 passes the large-diameter portion 79A of the support hole 78 formed in the upper surface plate 77 through the head 136 of the corresponding support screw 135 and then moves the front panel 60 to the left as viewed from the front, When the support screw 135 moves to the small diameter portion 79B side and the lip of the small diameter portion 79B is hooked on the head 136 of the support screw 135, the front panel 60 is similarly supported in a suspended form. At this time, the mounting plate 75A at the lower end of the front panel 60 is applied to the front surface 31A of the bottom plate 31 of the machine room 11 in a state where the insertion hole of the screw 76 and the screw hole 137 are aligned. It is fixed by screwing into.
On the upper side of the front panel 60, the head 136 of the support screw 135 is only supported by being fitted into the daruma-hole-like support hole 78, but in particular, the daruma-hole-like support hole 78 is set sideways. Compared with the case where the same dimple hole is formed in the front-rear direction (vertical direction), it is possible to reliably prevent the upper end side of the front panel 60 from falling forward when subjected to vibration or the like.

When the front panel 60 is thus mounted, a mounting recess 81 is formed between the support frame 120, the front panel 60, and the left and right cover panels 110 on the front side of the upper chamber 40U of the machine room 11, and this mounting recess. In 81, the operation panel 80 is mounted in an oblique posture with the upper end side retracted to the back side.
On the other hand, when removing the operation panel 80, the front panel 60 of the lower chamber 40D is first removed by the reverse procedure to the above, and then the screw 53 that has fixed the lower end mounting plate 109 is removed, and the upper end is the rear side. The latching portion 127 of the upper surface plate 105 is removed from the latching portion 127 of the support frame 120 and the left and right cover panels 110 are subsequently removed to the front side.

As described above, according to the present embodiment, the operation panel 80 including the left and right cover panels 110 is large and relatively heavy, but the operation panel 80 is attached to the support frame 120. Since it can be hung on and supported by the stopper 127, the operation panel 80 can be supported at the normal position with one hand, and the screwing operation can be performed with the other hand. That is, it is possible to perform the mounting work by one worker, and the workability is excellent. Further, since the operation panel 80 can be positioned while being slid along the support frame 120, the positioning operation can be easily performed.
Since the latching portion 127 is provided on the existing support frame 120 and is formed by simply bending the lower end of the front plate 126 of the support frame 120 to the back side at right angles, the latching portion 127 is provided. It can cope with low cost.

  Since the operation panel 80 is arranged in a form accommodated in a mounting recess 81 provided on the front surface of the upper chamber 40U of the machine room 11, it is possible to avoid foreign objects from touching the surface of the operation panel 80 as much as possible. Is done. Further, since the operation panel 80 is arranged in an oblique posture with the upper end retreated to the back, the operation on the operation unit 88 and the visual observation of the display unit 89 are easy.
